Configuring Express 4.0 routes with socket.io

Question

I have created a new Express application. It generated app.js for me and I have then created the following index.js bringing in socket.io:

var app = require(\'./         


        

Answer 1

The route:

const Router = require('express').Router

const router = new Router();

router.get('/my-route', (req, res, next) => {
    console.log(req.app.locals.io) //io object
    const io = req.app.locals.io
    io.emit('my event', { my: 'data' }) //emit to everyone
    res.send("OK")
});

module.exports = router

The main file:

const app = require('express')()
const server = require('http').Server(app);
const io = require('socket.io')(server)
const myroute = require("./route") //route file dir

app.use(myroute);

server.listen(3000, () => {
    console.log('¡Usando el puerto 3000!');
});

app.locals.io = io
